How To Rotate 180 Degree Video For Display In I.MX8X

jran — Mon, 23 Nov 2020 13:58:37 GMT

Hello, We have designed a i.MX8QXP based product with an LVDS display.

Due to mechanical constraints, we had to mount the display upside down. Now we want to rotate the screen 180 degrees in software.

We have found that weston can do display rotation. But that doesn't include the terminal, boot logo etc.
Rotation via /sys/class/graphics/fb0/rotate seems to do nothing.

How would one go about to rotate the display?

I found the following thread regarding basically the same thing: https://community.nxp.com/t5/i-MX-Processors/How-To-Rotate-90-Degree-Video-For-Display-In-I-MX8X/m-p/1029668
But the patch sent out in that thread doesn't seem to be available.
